Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. pgx.CopyFromRows transforms a slice of row slices into a CopyFromSource interface that sequentially yields values
  2. pgx.CopyFromRows reports nil error and finishes iteration when all rows are consumed
  3. pgx.CopyFromSlice generates CopyFromSource rows using an index-based mapper function
  4. pgx.CopyFromSlice propagates generator errors via Values and preserves error state in Err
  5. pgx.Batch initial length is zero and increases as queries are queued
  6. pgx.Batch.Queue records the parameterized SQL query and arguments into QueuedQuery
  7. pgx.QueuedQuery supports configuring Exec, Query, and QueryRow execution callbacks
  8. pgx.Identifier sanitizes multipart SQL identifiers and escapes embedded quotes
